Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed November 16, 1918. Serial No. 262,775.

To all whom it may concern:

Be it known that I, TAKEJIRO KUsUDA, a subject of Japan, resident of No. 17 Honden Samban Cho, Nishi Ku, in the city of Osaka, Japan, have invented certain new and useful Improvements in Belts, of whichthe following is a specification.

My invention relates to a belt formed from a broad iece of hemp, cotton or any other fabric. leather, or the like. by folding lengthwise from one side of the plece a desired width once or twice or more times either alternately or in one direction in winding way, but always leaving a certain unfolded. part; then fastening the folded part by sewing it lengthwise in several lines; then folding the unfolded part over the stitched part in one or two or more layers and fastening the new layer or layers to the stitched part by sewing lengthwise but at places other than where the inner layers have already been sewed; and if there is still unfolded part remaining, then folding it over stitched part in one or more layers and sewing as before, until the whole piece has been folded and stitched, the belt thus produced not being sewed all at once but layer by layer, and the stitches becoming closer and closer in the inner layers. 'The obiect of this invention is to obtain an ideal belt in which the whole fastening threads do not as in belts' of this kind hitherto manufactured. get rotten all at the same time by paint applied thereto to prevent their slipping over the pulleys; in which even' if the threads which fasten the. outer or surface layer get worn, the internal layers are kept intact being sewed layer by layer. so that there is no danger of the layers becoming loose; in which when the. surface layer becomes damaged it can be taken off and the remaining layers be used as a belt and is just as good as a new one; then the next layer can be taken off and the remainder be again used as a belt. and so on. for several times. which being stitched layer by layer from the innner layers to the outer layer. is very strong, does not stretch and bears the strain well: and in which one half the layers being less frequently stitched than i the other half. are soft. and consequently well fit the pulleys and transmit. power eflieiently.

The accompanying drawings show some examples of belts made according to my invention in which Figure 1 represents a belt which is made by folding a fabric in winding Way and in which various layers being broken off, the stitches .in each layer are shown.

Fig. 2 is a cross section of Fig. 1. Figs. 3 and 4 show belts also made in a=-cordance with my invention, the fabric being folded in different ways.

In order to carry my invention into practice, take a broad piece of hemp, cotton or any other woven fabric, fold lengt-hwise'a desired width one or more times commencing with one side of the fabric, and sew the folded part lengthwise. Then wind or fold the part remaining on the stitched part and sew as before but at different places. Repeat this process several times until the whole'widt-h of the fabric is folded and sewed, and thus a belt is produced.

To describe my invention more particularly with reference to the accompanying drawings, as shown in Figs. 1 and 2, first double lengthwise a desired width of one side of the fabric and fasten the two layers (a) and (b) sewing on the lines (A); then fold the remaining part of the fabric on the sewed part and sew the new layer (0) together with the layers (a) and (b) on the lines (B); again fold the remaining part on the sewed part and sew the new layer (d) together with the layers (a), (b) and (c) on the lines (C); again fold the still remaining part of the fabric on the sewed part and sew the new layer (e) together with the layers (a), (b), (c) and (d) on the lines (D) and thus form a belt.

Figs. 3 and 4. show sections of belts also formed according to this invention, the piece of fabric being folded alternately instead of winding.

Besides the above, my invention can be further modified by first winding or folding alternately several layers and sewing these layers as on the lines (A), then folding thereon one, or two layers, either alternately or in winding way and sew the layers as on the line (B), and'so on.

I am aware that before my invention I and then sewed. Thus, if the sewing threads become rotten by the paint put on the belt to prevent its slipping on the pulleys or worn by friction, the layers of fabric which compose the belt will be separated Y into pieces-and will become useless as a belt.

Now, according to my invention, as the belt is stitched by one or a few layers at one time from the inside toward the outside, even if the sewing threads appearing on the outside wear out, it does not-affect the inner layers. When such threads or the outer layer is worn out, the outer layer can be off several layers is always less than the number of stitches appearing on the other surface, one surface is always softer than the other, which makes the contact of the belt with the pulleys very satisfactory, preyenting the slipping of the. belt. Thus, this invention is mentioned advantages.

My invention can be modified in several ways without departing from its spirit.

1. A belt formed of a plurality of'layers of flexible material secured together by rows of stitches, the number of rows of stitches at one side of said belt being greater than at the other side thereof.

2. A belt formed of a plurality of layers of flexible material secured together by rows of stitches, the first two layers havlng an equal number of rows of stitches at each side of ,thebelt, and each additional layer being secured by rows of stitches passing entirely through the belt, whereby with every additional layer the number of rows of stitches is larger than at the other. a
